Answer the following questions. What type of rocks generally comprise a Ridge-and-Valley terrain? Why do the ridges and valleys that form in such an area not generally correspond to anticlines and synclines? What beneficial purpose do you think mountain building provides for human-kind?
Answer and Explanation:
Ridges and Valley topography came into shape because of the alternate presence of soft rocks and hard rocks. In fact, ridges and valley terrain are a great source of sediments resulting from human activities and by natural phenomena.
Anticlines and synclines are each half of the fold moves away and towards the crest respectively. Since, the processes are entirely different and are not related, this explains that ridges and valleys generally do not correspond to anticline and synclines.
The mountain building serves many purposes for human beings. They provide waterfalls, rainfalls, regulates climate changes, serves as a water source, helps in keeping the fertility of soil in check and maintains it.

changes in Earth-Sun relationships, namely Earth's orbit around the sun, axial rotation, and axial tilt.
topographic changes from orogeny, erosion, and mass movement.
cyclical changes in solar irradiance caused by increases and decreases in sunspot activity.
increases and decreases in atmospheric gases and aerosols, primarily caused by natural activity, such as volcanic eruptions and changes in net primary productivity.
tectonic changes in continental positions
Milankovitch cycles refer to changes in the Earth-Sun relationships caused by variations in the Earth's orbit, axial rotation, and axial tilt, affecting the climate and leading to cycles of ice ages and warm periods.
Explanation:Milankovitch cycles refer to changes in Earth-Sun relationships, which are specifically caused by variations in the Earth's orbit around the sun, axial rotation, and axial tilt. These changes lead to long-term alterations in the sunlight Earth receives, affecting climate over thousands of years. For example, the axial tilt changes over around 41,000 years from 22.1 to 24.5 degrees and back. When the tilt increases, summers get warmer and winters colder, contributing to the start and end of ice ages. However, they do not refer to topographic changes, solar irradiance changes due to sunspot activity, or changes in atmospheric gases and aerosols. The concept of Milankovitch cycles is primarily used in the field of paleoclimatology.

Milankovitch cycles refer to changes in Earth's relationships with the sun, including Earth's orbit, axial tilt, and axial rotation. These changes, derived from the theory developed by Milutin Milankovitch, result in long-term climate variations on Earth.
Explanation:The Milankovitch cycles primarily refer to the changes in Earth-Sun relationships that include Earth's rotation, axial tilt, and the shape of its orbit around the sun. Serbian engineer and mathematician Milutin Milankovitch developed this theory, which explains long-term climate changes on Earth. His theory is based on three parameters: Eccentricity, Obliquity, and Precession. Eccentricity is the variation in the shape of Earth's orbit from nearly circular to elliptical over about 100,000 years. Obliquity pertains to the change in axial tilt over around 41,000 years, and Precession refers to the gradual shift in the direction of Earth's axial rotation over roughly 26,000 years. Together, these parameters resulting in Milankovitch cycles are thought to be a significant driver of Earth's long-term climate variability.

What are the main types that geologists classify rocks into?
Why do mountains form around big bend
Answer:
The bends causes the overlaying of a crustal layer upon other layer. It results the formation of mountain on the overlying layer.
Explanation:
The big bends on the earth crust are the big faults. This fault formed due to the overlaying of a layer with other layers. The overlying crustal layer has deposits of lands on it and forms big mountains. This is a continuous and slow process. Sometimes the tectonic plate movement results in a sudden rise of some lands, and this forms new tabletop land and also dome mountains. The mountains are always formed due to the fault of the crust which are the bends on the earth. The mountains also formed due to a volcanic eruption. Such mountains are known as volcanic or igneous mountains. This is the very reason the mountains form around big bends

Name the gases responsible for global warming. Discuss causes and effects of global warming on global climate.
Answer:
Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect" — warming that results when the atmosphere traps heat radiating from Earth toward space.
Certain gases in the atmosphere block heat from escaping. Long-lived gases that remain semi-permanently in the atmosphere and do not respond physically or chemically to changes in temperature are described as "forcing" climate change. Gases, such as water vapor, which respond physically or chemically to changes in temperature are seen as "feedbacks."
Gases that contribute to the greenhouse effect include:
Nitrous Oxide
Methane
Water Vapor
Carbon Dioxide

The following sedimentary rock is a rock made from mud (it is a shale). Mud accumulates in many places on earth including the deep ocean, swamps, lakes, etc. Did this mud accumulate in the ocean or on the continent?
Answer: In the ocean
Explanation: Shale is a type of sedimentary rock that is most commonly found, consisting of mud, more specifically, mud particles, i.e. quartz particles and minerals. These particles are applied by water stream, are suppressed and deposited in quiet parts of the water surface. Those water areas where mud is deposited and suppressed can be lakes, lagoons, ocean depths.
the movement of water within the surf zone that parallels the shore is called ----------------
The movement of water parallel to the shore within the surf zone is known as longshore current, which, along with the associated sediment movement called longshore drift, plays a key role in coastline shaping.
The movement of water within the surf zone that parallels the shore is called longshore current. This current is generated by waves that approach the shoreline at an angle, causing the water to move along the shore as they break in the surf zone.
The process by which this motion results in the movement of sediments, such as sand, along the coast is known as longshore drift. These processes play a crucial role in shaping coastlines and creating various coastal features like spits and baymouth bars.
The longshore drift is responsible for the transport of a significant amount of sediment along coasts worldwide, which can lead to the development of specific depositional landforms.

Examine the relationship between social, economic, political and natural capital involved in the oil trade. (at least 200 words)
Oil is the most demanded natural resource after water. It is still the main source of fuel and is directly linked to the economic progress of the 21st century. Oil-rich nations use this as a social capital, capable of generating wealth and influencing global geopolitical dynamics. Oil is so important that price changes impact stock markets and cause large variations in financial market investments. Recent history shows that oil is a resource that is eventually used politically - as bargaining power - by the nations that hold it, as was observed in the OPEC cartel in the 1970s.

Select one:
a. force due to gravity
b. amount of water
c. geologic age of rocks
d. angle of the slope

Select one:
a. Dam construction
b. Building Construction
c. Road construction
d. Agriculture
Question 44
Which type of sediment deposit can fail and lead to a mass wasting event when the amount of water is decreased between the grains?
Select one:
a. boulders
b. silt
c. clay
d. sand
Answer 40: d. Water lowers strength and cohesion.
Explanation: The most ideal approach to comprehend this is by taking clayey soil and adding water to it. You will see that earth without water is an intense week with great quality. On the off chance that you add water to the blend, the dirt will have lower straight however it by hitting it with the mallet, it will really be somewhat moldable. Along these lines the quality of the strength and cohesion will get lower with lack of water.
Answer 41: a. The soil expands and contracts, lifting particles and dropping them a slight distance downslope.
Explanation: Creep, in geography, slow downslope development of particles that happens on each slant secured with free, endured material. Indeed, even soil secured with affectionate turf creeps downslope, as demonstrated by moderate however determined tilting of trees, shafts, tombstones, and different articles set into the ground on slopes. So the dirt extends and contracts, lifting particles and dropping them a slight separation downslope.
Answer 42: c. The geological age of the rocks.
Explanation: Mass squandering happens when the dirt/shake particles that are endured can't be held together and along these lines slide down the outside of an edge. In this way power because of gravity pull the unconsolidated issue down the slant. The measure of water in connection to the stone/soil substance adds to this. Free shake particles will slide effectively because of water. Dirt ingests the water somewhat however in abundance can surrender. The point of the slop chooses how quick squandering can happen. A precarious incline will cause mass squandering effectively when contrasted with a delicate slant.
Answer 43: c. Road contraction
Explanation: Road compression is the most widely recognized explanation behind mass squandering. Most street development takes puts by slicing through the bedrock-leaving the newly cut roadway uncovered. On the off chance that there is a blamed territory or region that isn't well-vegetated or essentially bedrock strata with a lofty incline, mass squandering can happen. To maintain a strategic distance from this, joining is normally done which incorporates fixing the newly cut shake body surface.
Answer 44: d. sand
Explanation: The definition is "an immersed soil mass moving by liquidity down a slant" in light of the fact that "a soaked soil mass" is certifiably not a fluid. Note that both mudflows and avalanches are made out of shake, earth, and garbage. The contrast in the measure of water they contain.
The strength and cohesion of clay-rich soil decrease with water addition, contributing to mass wasting. Freezing, thawing, wetting, and drying lead to soil creep, and factors like gravity, water content, slope angle, and anthropogenic changes like road construction affect mass wasting. Geologic age of rocks doesn't affect mass wasting, and sand is susceptible to failure when it dries out.
The addition of water to clay-rich regolith or soil generally lowers both the strength and cohesion of the material, making the correct answer (d) Water lowers strength and cohesion. For the question of how freezing, thawing, wetting, and drying contribute to soil creep, they cause the soil to expand and contract, which lifts particles and drops them downslope, thus (a) The soil expands and contracts, lifting particles and dropping them a slight distance downslope is correct. Factors affecting mass wasting include gravity, water content, and the slope angle. The geologic age of rocks does not directly affect mass wasting, making (c) geologic age of rocks the correct choice for the unrelated factor. The most common anthropogenic cause of mass wasting is (c) Road construction, as it can alter landscapes significantly. Lastly, when the amount of water decreases between the grains, sand deposits can fail and lead to mass wasting events, which makes (d) sand the right choice.

In a hypertonic solution, water flows through aquaporins embedded in the plasma membrane of the cell. This type of transport is best known as which if the following? A, Osmosis B. Active transport C. Facilitated diffusion D. Diffusion tS am a ati ti36of teisea
Answer:
In the given question, out of the four options
Option C. Facilitated diffusion
is correct.
Explanation:
In any hypertonic solution, flow of water is through the transporting channels known as 'aquaporins' which are embedded in the plasma membrane of the cell. Such type of transport is passive transport or passive movement of ions or molecules through a particular transmembrane protein integrated in it. This type of transport can also be referred to as passive mediated transport or commonly known as facilitated diffusion.
In a hypertonic solution, water moves through aquaporins in the cell membrane in a process called osmosis, a type of passive transport that plays a crucial role in regulating the internal environment of the cell.
Explanation:In a hypertonic solution, water moves through aquaporins in the cell membrane, a process best known as osmosis. This is a type of passive transport, where water molecules diffuse across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. Aquaporins accelerate this process by facilitating the rapid transport of water molecules, helping to maintain cellular integrity or adapt to changes in solute concentration in the extracellular environment. Osmosis plays a crucial role in the movement of water in and out of cells, highlighting the importance of cellular membranes and transport proteins in regulating the internal environment of the cell.

What defines the upper and lower boundaries of subalpine ecosystems in California, and how do these vary across the state? (word limit 150)
Answer and Explanation:
the upper boundary of sub alpine ecosystem is known as tree line and lower boundary of sub alpine ecosystem is known is montane zone the tree line is the edge of habitat at which trees are capable of growing it is found at very high elevation beyond this there is no life of treesthe upper montane zone is vegetarian type generally found above the mixed coniferous forest and bellow the sub alpine forestHOW DOES IT VARIES ACROSS THE STATE :
the marginal conditions make the sub alpine ecosystem sensitive to environment change the long lived nature of the sub alpine species make the zone a good study systemFinal answer:
The upper and lower boundaries of subalpine ecosystems in California are defined by climatic conditions such as temperature and precipitation, as well as by biotic factors including the presence of specific plant species adapted to these conditions. These boundaries vary across the state due to gradients in elevation and local climate variations.
Explanation:
In California, the subalpine ecosystem is typically found at high elevations just below the alpine zone. The lower boundary is often characterized by the transition from montane forests, which include species like ponderosa pine and white fir, to subalpine forests dominated by species such as lodgepole pine, mountain hemlock, and subalpine fir. The upper boundary is marked by the point at which trees can no longer grow due to the extreme environmental conditions, transitioning into the alpine zone. Across California, these boundaries are not static and shift with changes in latitude, elevation, and aspect (the direction a slope faces), all of which affect local climate conditions, resulting in variations in the flora and fauna that can thrive in these areas.
